Costco Tuxedo Cake Recipe

If you like the recipe, Please Share it!

This is the first Costco-inspired recipe I’m sharing on my blog. I’m a big fan of Costco and have made many copycat recipes based on their products. I think everyone knows the Costco Tuxedo Cake, a delicious black and white layered cake that used to cost $16.99. At least, that’s what I remember, since I haven’t been to Costco lately.

The black cake layers and white frosting give the cake its “Tuxedo” name. It looks gorgeous once you finish and assemble it. The cake does take some time to make— it took me over an hour and a half the first time. But it’s so delicious with the creamy frosting in the middle, so it’s worth it.

I made this copycat Costco Tuxedo Cake with layers of chocolate cake and creamy white frosting, topped with a glossy chocolate glaze. For the chocolate cake, I used flour, sugar, cocoa powder, baking powder, baking soda, salt, buttermilk, vegetable oil, eggs, and vanilla extract. The frosting is made from unsalted butter, powdered sugar, heavy cream, and vanilla extract. The cake is finished with a glossy chocolate glaze made from semi-sweet chocolate chips and heavy cream.

The cooking was fun, even though it got a little messy! You can also customize the cake with your favorite toppings, like fresh fruits or extra cream on top.
